IMO numbers are issued in broadly chronological blocks. Within 500 either side of 5347245 this registry holds 9 other vessels, whose median build year is 1956 and which range from 1905 to 1962. That places this hull’s registration in the same part of the series, consistent with its recorded build year of 1957.
Its IMO number, 5347245, carries its own check digit. The first six digits are weighted seven down to two and summed — 5×7 + 3×6 + 4×5 + 7×4 + 2×3 + 4×2 = 115 — and the last digit of that total, 5, must equal the seventh digit, 5. It does, so this number is well formed.
